General Description The DP8228/DP8228M, DP8238/DP8238M are system controller/bus drivers contained in a standard, 28-pin dual in-line package. The chip, which is fabricated using Schottky Bipolar technology, generates all the read and write control signals required to directly interface the memory and input/output components of the 8080A microcomputer family. The chip also provides drive and isolation for the bidirectional data bus of the 8080A microprocessor. Data bus isolation enables the use of slower memory and input/output components in a system, and provides for enhanced system noise immunity.
